PDNMESH(1) PdnMesh Manual PDNMESH(1)NAMEpdnmesh - A 2D finite element mesh generator and solverSYNOPSISpdnmesh[options] [-i input file]DESCRIPTIONpdnmeshis a 2D finite element problem solver. It generates the Delau- nay triangulation of an input point set and afterwards, it will solve the problem. Apart from the points, the set of edges and the boundaries should be specified in the input file. This is a beta release. Most of the options can now be changed using the GUI. So do not expect the command line options to work properly. Please report bugs topdnmesh-bugs@lists.sourceforge.net.OUTPUTThe program can generate Encapsulated Postscript files of the mesh, contours of potential and gradient and ASCII files of the mesh. In text only mode, by default it will generate the mesh and contour files. If a display is available, the program can also display its re- sults on the screen. It can display the equipotential contours as well as the gradient.OPTIONSpdnmeshaccepts the following options:-h,-?Print help.-VPrint the currently installed version ofpdnmeshon the stan- dard output.-sUses the sparse matrix solver instead of the full matrix solver (for Poisson Equation only).-aVALUESets the minimum area of a triangle to be split toVALUEThe area is taken with respect to local coordinates, NOT the input coordinates. The local coordinate system is enclosed in a 2 by 2 square centered at origin.-AVALUESets the maximum area of a triangle to be split toVALUEThe area is taken with respect to local coordinates, NOT the input coordinates. The local coordinate system is enclosed in a 2 by 2 square centered at origin.-cVALUESets the number of contour lines drawn toVALUEan integer.-iFILEReads the input file given byFILEwhich should be in the cor- rect format given by pdnmesh_input(5).-d(contour|grad|fill)By default displays either the contour plot, gradient plot or colour fill.-e(poisson|helmholtz|helmin|helmk|helmbeta)Selects the solver to use.poisson: Poisson Equation.helmholtz: Homogeneous Helmholtz Equation.helmin: Inhomogeneous Helmholtz Equation (using edge elements).helmk: Find cutoff frequency given propagation constant.helmbeta: Find propagation constant given cutoff frequency.-vPrint verbose output.-nxDo not open graphical display. This is used when the program is run in text mode.SEEALSOpdnmesh_input(5)COPYRIGHTCopyright (C) 2001-2005 Sarod Yatawatta Permission to use, copy, modify, and distribute this software and its documentation for any purpose and without fee is hereby granted, pro- vided that the above copyright notice appear in all copies and that both copyright notice and this permission notice appear in supporting documentation.
